Wellco, as a general contractor, manufactures industrial and civil buildings. Wellco can provide a turnkey service, including the development of an architectural study according to the client’s needs, the structural general design and construction, supply, fabrication, coating system (galvanized or painting), transportation and installation.

For more than 30 years Wellco has manufactured steel structures for power generation buildings (including power plants in Termoli and Ferrara, Italy, and the Isle of Sakalin, Russia), and the oil industry, including pipe racks and process structures. Wellco also has wide-ranging experience in the manufacture of steel structures for plant refurbishment projects.

Engineering and supply of steel structures

Our main scope of work includes:

  • Heavy weight steel structures (pipe racks; process structures; electro welded profiles)
  • Medium weight steel structures (shelters; platforms; pipe supports)
  • Light weight steel structures (rectangular / circular walkways; rectangular / circular handrails; stairs and ladders)
  • Roof and wall claddings (sandwich panels; steel sheets for roof and wall; flashings; gratings and steps)
  • Doors, main doors and windows (steel frame – REI – blast resistant)

Design and engineering of steel structures

Wellco uses its industry know-how in the design and engineering of its products in order to better serve its customers. Clients are supported in the preliminary stages with feasibility studies, drawings and technical documentation, to provide the best solutions at a technical and commercial level. This groundwork enables structures to be streamlined in terms of weight, and also facilitates efficient transport, storage and assembly operations. Wellco supplies steel structures all around the world.

The structural design includes the following stages:

  • Feasibility studies and pre-dimensioning
  • Design according to European standards (we have created around 10,000t of structures in Poland with Polish Norms), American standards (we have created 5,000t with Chilean Norms)
  • Calculation report either for the steel structures or for reinforced concrete
  • Joint development through localised calculation report stamped and signed by a certified engineer
  • Architectural drawings
  • General assembly drawings
  • Shop drawing
  • Erection drawings
  • Drawings of architectural details (roof and wall panels, flashings, doors and windows)
  • Technical assistance during installation

We use the following software:

  • Calculation software: SAP 2000, ETABS, MASTERSAP, ROBOT, STRAUS
  • 2/3D software software: Autocad; Tekla Structure 16 (it is possible to convert files: PDS and PDMS), Pro Steel 3D, TecnoMetal

Norms and standards

Here are some examples of our projects and the relevant enforced norms:

  • Algeria D.T.R.-B.C. 2-41, D.T.R.-B.C. 2-44, RPA 99, RNV 99
  • Chile: ACI 318-99 / NCh427 / NCh-433.Of96
  • Polonia: PN-Norm
  • Russia: SNIP and GHOST
  • Europe: EUROCODICE
  • Italy: D.M. 2008

Steel structure supply includes:

  • Supply and pre-fabrication of steel structures
  • Non-destructive tests (NDT)
  • Superficial treatments
  • Quality control – expediting
  • Quality control plan – inspection book

Quality controlled manufacturing

All phases of our work (particularly those relating to the manufacture and surface treatments) are followed by Wellco’s Quality Office, and special attention is given to the certification of all materials with appropriate documentation attesting the provenance and traceability. Wellco’s quality system is conceived and designed in respect of the rules of UNI EN ISO 9001 and UNI EN ISO 3834.

Our highly specialised staff work according to set processes and practices to ensure the identification and tracking of the product throughout every step of manufacturing and testing.

Each product is subject to final testing, which may be certified either internally or in the presence of the customer’s supervisors or official authorities.

Blast and bomb-resistant doors and windows

In recent years we have collaborated with the University of Padua in the study of blast and bomb-resistant buildings and accessories, including windows and doors.

Together we have developed numerical and experimental models to study the behaviour of such structures in case of explosion. In fact, we have built and are currently building numerous structures with blast-resistant characteristics in Algeria, Congo and many other locations.
